Salix lasiolepis is commonly found growing in canyons, along pond shores, and in swamps.[1][2]
The core range of the Arroyo Willow, (var. Bigelow's Willow) is all of western California, (the Coast Ranges, and most of central northern California), extending into southwest Oregon, and extreme north Baja California at the south.[3] The var. S. lasiolepis var. lasiolepis occurs in disjunct moderate sized locales: southwest Idaho, the Mogollon Rim–White Mountains across Arizona's transition zone, the coast range in northwest Oregon, central Washington, two northern mountain regions of New Mexico and two mountain regions of Coahuila.[4]
Salix lasiolepis is a deciduous large shrub or small tree growing to 10 m tall. The shoots are yellowish-brown, densely hairy when young. The leaves are 3.5–12.5 cm long, broad lanceolate, green above, glaucous green below covered at first with whitish to rusty hairs below which gradually wear off through the summer. The flowers are yellow catkins 1.5–7 cm long, produced in early spring.[2]
